SPECIFICATION forming part of Letters Patent No. 243,647', dated November 1, 1881,

Application tiled June 20, 1881. (Model.)

To all whom it may concern:

Be it known that I, JOHN C. CLrME, a citizen of the United States, residing in the city of Philadelphia, in the county of Philadelphia and State Pennsylvania, have invented certain new and useful Improvements in Door and other Bolts, of which the following is a specification, reference being had to the accompanying drawings, wherein- Figure l is a front elevation of my improved bolt. Figs. 2 and 3 are rear elevations of the same, illustrating the parts thereof in two dit"- ferent positions. Fig. et is a detail perspective of the operating-cam or eccentriclever. Fig. 5 is a similar view ofthe bolt-bar. Fig. G is a longitudinal section of the bolt with knob attachment. Fig. 7 is a broken sectional view of the samewithblind knob attachment.. Fig. Sis a broken sectional perspective with key. Fig. 9 ls a broken elevation, showing alarm attachment. Fig. 10 is an elevation, partly in section,ofa modification of my invention 5 and Fig. 11 is a broken longitudinal section of the same.

My invention has for its object to provide an improved bolt; and it consists in the novel combination, construction, and arrangement of parts, as hereinafter described.

Referring to the accompanying drawings, A represents a case for a bolt, formed with ears or lugs a a, through which pass screws c c' to fasten the same to a door or other ixture. Said case is also formed with a stud or pintle, a2, and with notches a3 c4 in its lower edge, at each end thereof, as shown.

B is the bolt-bar, theends of which are beveled, as shown at b b', and is provided with recesses b2 b2 and notches b3 b3 at either end thereof, as illustrated.

b4 is a central elongated slot formed in said bar, and through which passes or projects the stud d2. Said bar is also provided with shoulders b5 b adjacent to the ends of the slots b4.

C is a lever, having an opening, c, into which passes the stud a2 to form a pivotal bearing therefor. Said lever is provided with a cam or eccentric, c', fitting between and impingin g against the shoulders b5 b of bar B, as shown in Figs. 2 and 3. Said lever is also provided with a knob, D, having a threaded stem, d, which screws into the boss c2 of'said lever, and

otal bearing in the direction indicated by arrow g/ in Fig. 1. As soon as said lever begins to move, its cani e iinpinges against the shoulder b5 of bolt-bar B, and slides thelatter in thc direction indicated by arrow y, Fig. 2, until it enters the keeper. When said lever has been moved to such extent that the screw-stem d ot' knob D enters the notch c3 of casing its further movement is' thereby prevented, and the bolt B is then fully protruded into its keeper. The notch l)3 and recess b2 in the opposite end of said bar then register with said notch a in the casing. Hence said stein d, when it enters notch a3, also passes into notch b3, while the boss o2 of said lever enters said recess bzot the bolt-bar. rlhe knob D is then screwed down until it impinges against the face ofthe case, and by frictional contact therewith secures said lever tiXed in position and locks the bolt-bar in its keeper. By reason of the described registration of the notches as b3, and the receiving of the boss cin recess b2, the bo1t-bar and lever C are both locked together on the casing. Stich locking of said parts will oii'er great resistance to the pushing back ot' the bolt-bar from the outside ot` the door. To withdraw said bolt-bar, the knob D must first be unscrewed, the lever C may then be turned or moved in a reverse direction to that above described until stem d enters the notch 0.4 on the opposite side ofcasing A, when the barB is then fully retracted from its keeper and the door unfastened. As said stem enters said notch a4 the notch b3 and opening or recess b2 on the other end ot' bolt-bar then register with notch c4, and said stem passes into both said notches, while boss c2 enters recess b2, whereupon knob D is turned to lock the bolt-bar in its retracted position to prevent it accidentallyslipping into the keeper as the door is opened and closed.

It will thus be seen that the bolt is recipro` cated by simply moving the lever C from one side of the casing to the other, and said boltbaris locked both in its protruded and retracted positions.

Ifthe lever C is permitted to hang vertically, as shown in Fig. 3, the bolt-bar will be partially pushed into its keeper. In such position it affords a desirable catch or temporary bolt for the door fora person occupying a room and not wishing to be disturbed, but still not desiring to completely fasten the door.

If desired, the lever C may be formed with a pintle, G, havinga square end, g,which passes through the door, and to which is secured a knob, H, as shown in Fig. 6. The bolt is thereby converted into a door-lock having an outside knob attachment, and as long as the lever C and bolt-bar B are not locked, as described, the door may be opened and shut. in the ordinary manner.

Fig. 7 shows a modcation ot' the knob attach|nent,wl1erein the knob G is a blind knob, but is hollow and formed with an opening, g', in its face, through which a key, g2, is designed to pass to engage with the pintle G on lever (l, said construction forming a convenient form for a dead-latch.

1f desired, the blind knob attach ment may be dispensed with, and a key hole or opening formed in the door, as shown in Fig. 8, in which case the stud (t2 is provided with an aperture, h, and the lever C has an opening, h', as shown, for the key to engage with to retract the bolt from its keeper.

ln thelast-described constructions nospi ings are required to reversely turn the bolt-bar after the same has been moved h v theknob or keys, as is heretofore necessary in door-locks and dead-latches, for the reason that the lever C is of suticient gravity to perform that operation.

Figs. 8 and 9 show my invention applied to a door having an upper and lo u er bolt designed to be operated simultaneously. The bolt-bar is made in two parts, B B2, each having the central slot, b4, and 'shoulders b5 bfi. The lever C is provided with double cams or eccentrics, as shown, one for each holt-bar, and fitting becomparatively easy, and dispenses with the use ot' han ginglchains heretofore required.

If desired, an alarm may be connected to the bolt-case, as shown in Fig. 9, said alarm consisting ofa bell orcartridge secured by a screw, K, to a lug, k, depending from the bolt-case. When the bell or alarm is in use it is swung on its pivotal attachment until it is in line with the path of travel of'the knob D, so that it' the bolt be by any means withdrawn from its keeper by a person seeking to obtain entrance through the door to which the devices are attached, the movement ot' said bolt will canse the lever C to drop or move, and its knob D will strike the bell or cartridge L and sound an alarm.

The bar B is beveled at both ends, so that the bolt may be applied to any part of the door or other tixture, either on its inside or outside.

What I claim as my invention is- 1. In a door-bolt, the combination, of a casing having notches on its lower edge near its ends and a central stud or projection, a boltbar having acentral elongated slot and shoul- ,ders on each end ot said slot, and an eccentric or cam lever for operating said bolt-bar, suhstantially as shown and described.

2. The combination of casing A, bolt-har B, cam-lever (l, having locking devices D, substantially as and tor the purpose set forth.

In testimony thatI claim the foregoing l have hereunto set my hand this 18th day ot' May, A. D. 1881.
